Question

(PLS HELP ASAP <3)
a sample of oxygen gas occupies 600mL when the pressure is 900 mmHg, what is the pressure if the volume is increased to 800 mL​

Answers

  1. Answer:

    675 mmHg

    Explanation:

    The new pressure can be found by using the formula for Boyle’s law which is

    P_1V_1 = P_2V_2

    Since we’re finding the new pressure

    P_2 = \frac{P_1V_1}{V_2} \\

    We have

    P_2 = \frac{900 \times 600}{800} = \frac{540000}{800} \\ = 675

    We have the final answer as

    675 mmHg

    Hope this helps you
